TICKER TAPE TIMER, 12V AC

For timing motion in one dimension on a piece of paper in the form of dots spaced at equal interval of time, An electromagnet enclosed in a box operates on 1 2V AC through a pair of 4mm sockets. The screw shaped hammer on the armature mounted at the top of enclosure moves up/down with the changing polarity of electromagnet and leaves well defined dot on paper strip moving beneath carbon paper disc. Guides on top of enclosure assure smooth and straight movement of paper strip. Amplitude of vibration of hammer can be varied to get sharp dot and relative position of carbon discs with respect to paper tape adjustable for their optimum use. Includes a stand for mounting paper tape roll. Complete assembly mounted on a stable, non-skid base, Supplied complete with paper tape and carbon paper discs.

TORSION APPARATUS, HORIZONTAL

Searle's pattern. For investigating the torsional rigidity of rods of different materials and to demonstrate that the angle of twist of a given rod over a fixed length is proportional to the applied force. The apparatus consists of two parallel metal support rods with heavy cast metal legs at their either end. One of the legs has ball bearing mounted pulley wheel at its outer side with its spindle carrying split collet chuck for holding one end of test rod, while other end of the test rod supported through the clamping block on the other leg. When loaded with masses through the nylon cord wound on the pulley wheel, twisting couple if applied to the test rod. Two aluminium scales, graduated 30?; 0-30?x 1?, fixed on pillar supports are mounted on the metal support rods along its length. Also included are two pointers, which when clamped to the test rod along its length and adjacent to the scale, indicates the torsion produced in the rod at that point. Supplied complete with two test rods, one each of brass and steel, nylon cord and hook for carrying masses, but without masses.

TORSION APPARATUS, VERTICAL

Specially designed apparatus for investigation into the stress and strain accompanying the torsion i. e., torsion modulus of rigidity of the substance. The apparatus consists of a two long metal mounting rods located vertically on a T-shaped assembly and are jointed at the top through another square metal rod. Three adjustable angle measure attachments, graduated in degrees, are located vertically along the lengths of the rods for measuring degree of rotation of experimental rod under torsion at the desired positions. The bottom T-shaped assembly has a circular drum on to which is connected the weight pan on its either side through lightweight cord. The cord wound on the drum, with the weight pan suitably loaded, provides the necessary torque to the experimental rod. Chuck is provided at the top as well as bottom with tightening screws to firmly hold the experimental rod. Complete assembly mounted on a heavy cast metal tripod base with leveling screws. Includes two experimental rods - one each of brass and steel.
